EC number: 204-847-9
CAS number: 127-52-6
The following EC10 values were determined, based on mean measured concentrations: (1) hatchability: 1.93 mg/L (95% C.I.: 1.14 to 2.70), (2) mortality of fry not determined, NOEC: 0.25 mg/L, (3) fish body weight: 0.19 mg/L (C.I. not determined).
The NOEC (30 days) body
weight is selected for the chemical safety assessment, since it is the
most sensitive endpoint.
The analytical results
obtained during the study showed that the substance was instable within
3 days of exposure, under testing conditions, and depending on the test
time weighted averages were calculated based on HPLC measurements of
freshly prepared and solutions aged for maximum 3 days: 0, 0.13, 0.25,
0.71 2.42 and 6.16 mg/L. These values correspond to 33%,
28%, 36%, 54% and 62% of the nominal concentrations. The suitability of
the analytical method was verified by using QC samples at 0.1 and 10
mg/L, which showed recoveries of 92.8 (0.1 mg/L) to 94.5% (10 mg/L).
Furthermore, recoveries of freshly prepared solution at test start and
each re-newal were between 72.5% and 91.4%.
